  • Technical Features: 

    1.Balanced design with precisely calculated face pressure ratio to reduce face load and minimize heat generation.

    2.Standard seals feature silicon carbide (SiC) vs silicon carbide (SiC) pairing, delivering superior wear resistance and low friction for peak performance.

    3.Tungsten carbide seal rings for crystallizing/particulate media — delivering high wear resistance and strength.

    4.Externally mounted multi-spring design minimizes centrifugal effects for enhanced spring stability.

    5.Large-cross-section sealing rings maintain floatability while enhancing sealing performance.

    6.Eliminates internal flush, preventing product dilution.

    7.The highly reliable drive design effectively prevents slippage even on high-hardness shafts.

    Solution Selection:
    In general crystallizing media conditions, the Plan 02 heat-tracing option can be selected to prevent media crystallization. If conditions permit, the Plan 32 flushing option is also available.
